Time series graphs

Note that the comparison between Dylos and BAM readings is done for Dylos ≥ 0.5u with PM2.5 and Dylos ≥ 2.5u with PM10. You might think that comparing readings for Dylos ≥ 2.5u and PM2.5 might be more relevant, but this is actually not the case. The explanation is given in the experiment ' what is the dylos monitor actually measuring'.

Variation between stations

The next 2 graphics show the PM2.5 and PM10 raw values (in µg/m3) for different BAM stations (i.e. without the Dylos values) in Beijing, for the last 10 days. This is provided to ensure that there is not significant devitation between the various stations, especially considering that some are located on the road side, while others are in the living area.
